Colorimetric detection outshines other technology

With colorimetric detection, BACT/ALERT® culture media offers you sophisticated technology that outshines the rest. Specialized Liquid Emulsion Sensors (LES) at the bottom of each culture bottle visibly change color when the pH changes due to the rise in CO2 as it is produced by microorganisms. BACT/ALERT® 3D instruments measure the color changes every ten minutes and analyze the changes. Sophisticated algorithms, including a unique “threshold” algorithm, ensure early detection of micro-organisms. Even when bottles are delayed in transit, the visual color change helps you potentially identify positive bottles prior to entry into the system. That’s how you can be assured of accurate detection and rapid recovery of microorganisms from various sample types.

Technology and sophisticated algorithms help minimize false negatives due to delayed entry

Low false-positive rates

Visual, irreversible color change

Flexible media delivers reliable recovery

BACT/ALERT® culture media offers a comprehensive range of media bottles to ensure the rapid recovery of a wide variety of microorganisms including bacteria, mycobacteria, fungi, and yeasts. From various sample types including blood, sterile body fluids and sputum, BACT/ALERT® culture media can detect 98% of isolates within 72 hours*.

Safety & efficiency: trust the pioneer in plastic collection bottles

bioMérieux was the first to introduce revolutionary multilayer plastic bottles. Made of unique polycarbonate material, their triple-layer design ensures appropriate environment for recovery of microorganisms. These shatter-resistant bottles significantly improve safety in the laboratory by eliminating accidental spills, potential biohazard exposure and glass cuts. Because they weigh less, these bottles have the added benefit of reducing shipping and disposal costs. And – as numerous studies have shown – the bottom line is that you get all these clear advantages while still ensuring optimal performance in recovery and time to detection.
